Low Tire Pressure

Warning Light

Low Tire Pressure Position and

Tire Pressure Telltale

ONX4E040019

When the tire pressure monitoring

system warning indicators are

illuminated and a warning message

displayed on the cluster LCD display,

one or more of your tires is significantly

under-inflated. The Low Tire Pressure

Position Telltale will indicate which

tire is significantly underinflated by

illuminating the corresponding position

light.
If either telltale illuminates, immediately

reduce your speed, avoid hard cornering

and anticipate increased stopping

distances. You should stop and check

your tires as soon as possible. Inflate the

tires to the proper pressure as indicated

on the vehicle’s placard or tire inflation

pressure label located on the driver’s

side center pillar outer panel.

If you cannot reach a service station or

if the tire cannot hold the newly added

air, replace the low pressure tire with the

spare tire.
The Low Tire Pressure Telltale will remain

on and the TPMS Malfunction Indicator

may blink for one minute and then

remain illuminated (when the vehicle

is driven approximately 10 minutes at

speed above 15.5 mph (25 km/h)) until

you have the low pressure tire repaired

and replaced on the vehicle.

CAUTION

In winter or cold weather, the Low Tire

Pressure Telltale may be illuminated if

the tire pressure was adjusted to the

recommended tire inflation pressure

in warm weather. It does not mean

your TPMS is malfunctioning because

the decreased temperature leads to a

proportional lowering of tire pressure.
When you drive your vehicle from a

warm area to a cold area or from a cold

area to a warm area, or the outside

temperature is greatly higher or lower,

you should check the tire inflation

pressure and adjust the tires to the

recommended tire inflation pressure.

WARNING

Low pressure damage
Significantly low tire pressure makes

the vehicle unstable and can contribute

to loss of vehicle control and increased

braking distances.
Continued driving on low pressure tires

can cause the tires to overheat and fail.

8-15

TPMS (Tire Pressure

Monitoring System)

malfunction indicator

The TPMS Malfunction Indicator

will illuminate after it blinks for

approximately one minute when there

is a problem with the Tire Pressure

Monitoring System.
Have the system checked by an

authorized HYUNDAI dealer as soon as

possible.

NOTICE

If there is a malfunction with the TPMS,

the Low Tire Pressure Position Indicator

will not be displayed even though the

vehicle has an under-inflated tire.

NOTICE

The TPMS Malfunction Indicator may

illuminate after blinking for one minute

if the vehicle is near electric power

supply cables or radio transmitters

such as police stations, government

and public offices, broadcasting

stations, military installations, airports,

transmitting towers, etc.
Additionally, the TPMS Malfunction

Indicator may illuminate if snow chains

are used or electronic devices such as

computers, chargers, remote starters,

navigation, etc. This may interfere with

normal operation of the TPMS.

Changing a Tire with TPMS

If you have a flat tire, the Low Tire

Pressure and Position indicators will

come on. Have the flat tire repaired by an

authorized HYUNDAI dealer as soon as

possible or replace the flat tire with the

spare tire.

NOTICE

It is recommended that you do not

use a puncture-repairing agent not

approved by HYUNDAI dealer or the

equivalent specified for your vehicle to

repair and/or inflate a low pressure tire.

Tire sealant not approved by HYUNDAI

dealer or the equivalent specified for

your vehicle may damage the tire

pressure sensor.

The spare tire (if equipped) does not

come with a tire pressure monitoring

sensor. When the low pressure tire or

the flat tire is replaced with the spare

tire, the Low Tire Pressure Indicator will

remain on. Also, the TPMS Malfunction

Indicator will illuminate after blinking

for one minute if the vehicle is driven

at speed above 15.5 mph (25 km/h) for

approximately 10 minutes.
Once the original tire equipped with

a tire pressure monitoring sensor is

reinflated to the recommended pressure

and reinstalled on the vehicle, the

Low Tire Pressure Indicator and TPMS

Malfunction Indicator will go off within a

few minutes of driving.
If the indicators do not extinguish after

a few minutes, contact an authorized

HYUNDAI dealer.
Each wheel is equipped with a tire

pressure sensor mounted inside the tire

behind the valve stem (except for the

spare tire). You must use TPMS specific

wheels. It is recommended that you

always have your tires serviced by an

authorized HYUNDAI dealer.

Emergency Situations

8-16

You may not be able to identify a tire

with low pressure by simply looking at it.

Always use a good quality tire pressure

gauge to measure. Please note that a tire

that is hot (from being driven) will have a

higher pressure measurement than a tire

that is cold.
A cold tire means the vehicle has been

sitting for 3 hours and driven for less

than 1 mile (1.6 km) in that 3 hour period.
Allow the tire to cool before measuring

the inflation pressure. Always be sure

the tire is cold before inflating to the

recommended pressure.

WARNING

The TPMS cannot alert you to severe

and sudden tire damage caused by

external factors such as nails or road

debris.

If you feel any vehicle instability,

immediately take your foot off

the accelerator, apply the brakes

gradually with light force, and slowly

move to a safe position off the road.

WARNING

Tampering with, modifying, or disabling

the Tire Pressure Monitoring System

(TPMS) components may interfere

with the system’s ability to warn the

driver of low tire pressure conditions

and/or TPMS malfunctions. Tampering

with, modifying, or disabling the Tire

Pressure Monitoring System (TPMS)

components may void the warranty for

that portion of the vehicle.

Information

This device complies with Part 15 of the
FCC rules.

Operation is subject to the following three
conditions:

This device may not cause harmful
interference, and

This device must accept any
interference received, including

For safe operation, carefully read and

follow the instructions in this manual

before use.
(1) Compressor
(2) Sealant bottle
The Tire Mobility Kit is a temporary fix to

the tire and have the tire inspected by an

authorized HYUNDAI dealer as soon as

possible.

CAUTION

When two or more tires are flat, do not

use the tire mobility kit because the

sealant provided with the Tire Mobility

Kit must be used for only one flat tire.

WARNING

Do not use the Tire Mobility Kit to repair

punctures in the tire walls. This can

result in an accident due to tire failure.

WARNING

Have your tire repaired as soon as

possible. The tire may lose air pressure

at any time after inflating with the Tire

Mobility Kit.

Introduction

With the Tire Mobility Kit you stay mobile

even after experiencing a tire puncture.
The compressor and sealing compound

system effectively and comfortably seals

most punctures in a passenger car tire

caused by nails or similar objects and

reinflates the tire.
After you ensure that the tire is properly

sealed you can drive cautiously on the

tire (distance up to 200 km (120 miles))

at a max. speed of (80 km/h (50 mph)

in order to reach a service station or tire

dealer for the tire replacement.
It is possible that some tires, especially

with larger punctures or damage to the

sidewall, cannot be sealed completely.
Air pressure loss in the tire may adversely

affect tire performance.
For this reason, you should avoid abrupt

steering or other driving maneuvers,

especially if the vehicle is heavily loaded

or if a trailer is in use.
The Tire Mobility Kit is not designed

or intended as a permanent tire repair

method and is to be used for one tire

only.
This instruction shows you step by step

how to temporarily seal the puncture

simply and reliably.
Read the section “Notes on the safe use

of the Tire Mobility Kit”.

WARNING

Do not use the TMK if a tire is severely

damaged by driving run flat or with

insufficient air pressure.
Only punctured areas located within the

tread region of the tire can be sealed

using the TMK.

Emergency Situations

8-18

Notes on the safe use of the Tire

Mobility Kit

Park your car at the side of the road

so that you can work with the Tire

Mobility Kit away from moving traffic.

To be sure your vehicle will not move,

even when you’re on fairly level

ground, always set your parking brake.

Only use the Tire Mobility Kit for

sealing/inflation passenger car tires.

Only punctured areas located within

the tread region of the tire can be

sealed using the tire mobility kit.

Do not use on motorcycles, bicycles

or any other type of tires.

When the tire and wheel are

damaged, do not use Tire Mobility Kit

for your safety.

Use of the Tire Mobility Kit may not be

effective for tire damage larger than

approximately 4 mm (16 inch).
Please contact the nearest HYUNDAI

dealer if the tire cannot be made

roadworthy with the Tire Mobility Kit.

Do not use the Tire Mobility Kit if a tire

is severely damaged by driving run flat

or with insufficient air pressure.

Do not remove any foreign objects

such as nails or screws that have

penetrated the tire.

Provided the car is outdoors, leave

the vehicle in the ready (

) mode.

Otherwise operating the compressor

may eventually drain the car battery.

Never leave the Tire Mobility Kit

unattended while it is being used.

Do not leave the compressor running

for more than 10 minutes at a time or

it may overheat.

Do not use the Tire Mobility Kit if the

ambient temperature is below -30°C

(-22°F).

In case of skin contact with the

sealant, wash the area thoroughly

with plenty of water. If the irritation

persists, seek medical attention.

In case of eye contact with the

sealant, flush your eyes for at least 15

minutes. If the irritation persists, seek

medical attention.

In case of swallowing the sealant,

rinse the mouth and drink plenty of

water. However, never give anything

to an unconscious person and seek

medical attention immediately.

Long time exposure to the sealant

may cause damage to bodily tissue

such as kidney, etc.

(

indicator ON), switch on

the compressor and let it run for

approximately 5~7 minutes to fill

the sealant up to proper pressure.

(Refer to “Tire and Wheels” section

in chapter2)

. The inflation pressure of

the tire after filling is unimportant and

will be checked/corrected later.
Be careful not to overinflate the tire

and stay away from the tire when

filling it.

CAUTION

Do not attempt to drive your vehicle if

the tire pressure is below 200 kpa (29

psi). This could result in an accident due

to sudden tire failure.

Emergency Towing

Front

ONX4080019

Rear

ONX4H080002

If towing is necessary, have it done by

an authorized HYUNDAI dealer or a

commercial tow truck service.
If a towing service is not available in

an emergency, your vehicle may be

temporarily towed using a cable or chain

secured to the emergency towing hook

at the front (or rear) of the vehicle.
Use extreme caution when towing the

vehicle with a cable or chain. A driver

must be in the vehicle to steer it and

operate the brakes.
Towing in this manner may be done

only on hard-surfaced roads for a short

distance and at low speeds. Also, the

wheels, axles, power train, steering and

brakes must all be in good condition.

CAUTION

The driver must be in the vehicle for

steering and braking operations when

the vehicle is being towed. Passengers

other than the driver must not be in the

vehicle.

Always follow these emergency towing

precautions:

Place the ignition switch in the ACC

position so the steering wheel is not

locked.

Place the shift button in N (Neutral).

Release the parking brake.

Depress the brake pedal with more

force than normal as you will have

reduced braking performance.

More steering effort will be required

because the power steering system

will be disabled.

Use a vehicle heavier than your own to

tow your vehicle.

The drivers of both vehicles should

communicate with each other

frequently.

Before emergency towing, check that

the hook is not broken or damaged.

Fasten the towing cable or chain

securely to the hook.

Do not jerk the hook. Apply steady

and even force.

8-29

Your HYUNDAI vehicle may come

equipped with certain additional

emergency or roadside assistance

accessories that may be useful if a

problem occurs.

Fire Extinguisher

If there is small fire and you know how

to use the fire extinguisher, follow these

steps carefully.
1. Pull out the safety pin at the top of the

extinguisher that keeps the handle

from being accidentally pressed.

2. Aim the nozzle towards the base of

the fire.

3. Stand approximately 8 ft (2.5 m) away

from the fire and squeeze the handle

to discharge the extinguisher. If you

release the handle, the discharge will

stop.

4. Sweep the nozzle back and forth

at the base of the fire. After the fire

appears to be out, watch carefully

since it may re-ignite.

First Aid Kit

Supplies for use in giving first aid such as

scissors, bandages and adhesive tape,

etc. are provided.

Triangle Reflector

Place the triangle reflector on the road

to warn oncoming vehicles during

emergencies, such as when the vehicle is

parked by the roadside due to problems.

Tire Pressure Gauge

Tires normally lose some air in day-to-

day use, and you may have to add a air

periodically and usually it is not a sign of

a leaking tire, but of normal wear. Always

check tire pressure when the tires are

cold because tire pressure increases with

temperature.

To check the tire pressure, take the

following steps:
1. Unscrew the inflation valve cap that is

located on the rim of the tire.

2. Press and hold the gauge against the

tire valve. Some air will leak as you

begin and more will leak if you don’t

press the gauge in firmly.

3. A firm non-leaking push will activate

the gauge.

4. Read the tire pressure on the gauge

to see whether the tire pressure is low

or high.

5. Adjust the tire pressure to the

specified pressure. Refer to “Tires and

Wheels” section in chapter 2.

6. Reinstall the inflation valve cap.

Maintenance

9-16

Checking the Engine Oil Level

Engine oil is used for lubricating,

cooling, and operating various hydraulic

components in the engine. Engine oil

consumption while driving is normal,

and it is necessary to check and refill the

engine oil regularly. Also, check and refill

the oil level within the recommended

maintenance schedule to prevent

deterioration of oil performance.
Check the engine oil following the below

procedure.
1. Follow all of the oil manufacturer’s

precautions.

2. Be sure the vehicle is on the level

ground in P (Park) with the parking

brake set and the wheels blocked.

3. Turn the engine on and warm

the engine up until the coolant

temperature reaches a constant

normal temperature.

4. Turn the engine off, remove the oil

filler cap and pull the dipstick out.

Wait for 15 minutes for the oil to return

to the oil pan.

5. Wipe the dipstick clean and re-insert

it fully.

ONX4PH091002N

6. Pull the dipstick out again and check

the level. The level should be between

F (Full) and L (Low).

ONX4H090020

7. If the oil level is below L, add enough

oil to bring the level to F.

Use only the specified engine oil (Refer

to “Recommended Lubricants and

Capacities” section in chapter 2).

NOTICE

To prevent damage to your engine:

Do not overfill with engine oil. Add oil

in small quantities and recheck level

to ensure engine is not overfilled.

The engine oil consumption may

increase while you break in a new

vehicle and it will be stabilized after

driving 4,000 miles (6,000 km).

The engine oil consumption can be

affected by driving habits, climate

conditions, traffic conditions,

oil quality, etc. Therefore, it is

recommended that you inspect the

engine oil level regularly and refill it

if necessary.
